Sincerely, I do not recollect ever seeing [people come to blows over a parking spot]. Doubtlessly, it is an occasional thing that happens...but I call Strawman on your argument.
1. Do you know what a strawman argument is? It's not like there aren't a zillion other petty things people come to blows over.
2. Google search for "fight over parking spot".
There are even videos in the results so you can see with your own eyes.
